I was wondering is it possible to have a 3D actor's direction linked to a sprites frame number.

In otherwords I have a Compass sprite and wanted it to display the direction the 3D actor was facing.

Well, you can try something like this. Make a compass hand a sprite which will have its hotspot in the center. Also make it a square.
Then try some code similar to this (untested one).

Code: [Select]

var degrees = actor.DirectionAngle;  //returns in degrees the direction your 3d actor is facing

var tmp = Scene.GetNode("CompassHand");
tmp.Rotatable = true;

tmp.Rotate = degrees;

of course for this to work all the time, you'd have to create a script which you attach to your actor and where this will be in some
while loop.

Code: [Select]

#include "scripts\base.inc"

while (1)
{
   ... the provided code ...
   Sleep(10); //time how fast it should be updated without any Sleep your game will freeze
}

Hello.

Just startet working with Wintermute and also want to create something like a compass. I tried the code above and it works, but the rotation is very slow. It seems the game is updated only every second, although the Sleep function is set to suspend the script for only 20ms. Do you have an idea what's the reason or how to make the rotation work more fluently?

Can you post your code? The game is definitely updated more often.

So far the code is as follows:

Code: [Select]

#include "scripts\base.inc"

global Line = Game.LoadEntity("entities\new_entity\new_entity.entity");

Line.Rotatable = true;

while(true){

  var mouseY;
  var alpha;
  var rad;
  var deg;

  mouseY = Game.MouseY-300;
  alpha = mouseY/200;
  rad = Math.Asin(alpha);
  deg = Math.RadToDeg(rad);
  Line.Rotate = deg;
 
  Sleep(20);
}
The "needle" shall only be influenced by the Y position of the cursor.

If you add Game.Msg(deg); just before the sleep line, the game will be periodically displaying the calculated angle on screen. That way you can check what value your calculation returns.

Thanks. The calculation is correct.
I've copied the code into a new script and removed the old one. Suddenly the rotation works fluently    I think that's really strange *lol*
